Connection_Dropped IIS6
am 03.08.2007 02:56:16 von unknown
Hi,
We are running an ASP application in IIS6. This site used to run perfectly but over the last year we have been having increasing problems especially since we upgraded from II5 to IIS6 I think.
Symptoms:
...Connection_Dropped DefaultAppPool a lot for lots of pages
...System gets slower and slower
...Soft Artisans File up COM object crashes and reports that is can't be created in the ASP page
All of the above issues are fixed instantly once IIS is restarted and then it slowly gets worse until we have to do it again. The COM issue once it starts continues EVERY time until IIS is restarted.
I have looked around and it seems to be said that IIS6 shouldn't need to be restarted and should recycle the application pool or something.
This app will eventually get rewritten in .NET but that is more a long term solution not an immediate one and we need to fix this now. Would having a batch job restarting IIS every night help or be possible?
I have attached more info below which states the the asp.dll is unhealthy.
Any ideas would be greatfully received.
Cheers,
Steve

ISAPI 'C:\WINDOWS\system32\inetsrv\asp.dll' reported itself as unhealthy for the following reason: 'ASP unhealthy because 100% of executing requests are hung and 1% of the request queue is full.'.
For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
A process serving application pool 'DefaultAppPool' exceeded time limits during shut down. The process id was '3744'.

You have some sort of application instability/incompatibility which is
shown with IIS6 on Windows Server 2003.
Normally, I do not recommend restarting IIS because it really doesn't
"fix" anything. It just forces you to hobble along until you can
diagnose and fix the issue. You have indicated that you believe
rewriting the application in .Net is your prefered solution, in which
case you may not be interested in debugging the current application to
figure out its problem. But, that is a decision for you to make.
Hence, you can certainly restart IIS if you want -- just be aware that
it is not standard procedure nor does it indicate that IIS has an
issue. Restarting IIS is simply the easiest workaround that you have
determined for your application's issue. By no means is it a solution
nor does it indicate a problem with IIS -- you've never proven your
application to function on IIS6/Windows Server 2003. There are plenty
of broken applications that accidentally work well on IIS5/Windows
2000 -- it takes debugging to figure out if the problem is caused by
IIS, OS, or the application itself.
I believe that you are forced to restart IIS because you upgraded from
IIS5, in which case IIS6 is running in IIS5 Comptability Mode, and
there is no Application Pools to recycle. Hence, you have to restart
IIS, like IIS5.
You will need to run IIS6 in its native worker process isolation mode
to get Application Pool recycling benefits (i.e. schedule recycling of
application pool to avoid restarting IIS completely), but there is no
guarantee that your web application is compatible with worker process
isolation mode. Of course, you know that the web application already
has problems with IIS5 Compatibility Mode, so it's probably no worse
to try Worker Process Isolation mode to see if it "helps" you to
switch to restarting Application Pools instead of IIS entirely.
Finally, if you are interested to debug and fix the actual issue
instead of just restarting IIS, you may want to run a tool like IIS
State or DebugDiag when you encounter your error condition and post
the log file here. It gives us a memory backtrace of your issue and
allows us to see why you have ASP tied up and why the server slows
down.

Hey David, you rock. Thanks so much for taking the time to reply to my post.
There was a fractional misunderstanding though, my choice is not to rewrite the app, although that will happen down the track, I want to fix it and that is why I posted this. And I hate it that we have to restart IIS every day, it looks unprofessional on a whole bunch of levels.
The company that looks after the server keeps saying it is an application issue and we need to rewrite it (they are angling for the job) from scratch in .net and have no desire to try and fix it in any shape or form because of this. However I (the app developer) have never been comfortable with this bug as the system has been running really well for 8 years , stable and solid, hadn't changed much and the bug appeared from nowhere. I suspected it was infrastructure of some kind.
I think you are right that it is the introducton of IIS6 that is causing the problem. I had no idea that things might run differently and nothing was ever tested against IIS6, it was just migrated across with nothing said.
I am not sure what mode the server is running in whether it is iis5 compat or the other one.
I will follow your advice and get these debug tools run and see what comes up, and post the logs here. thanks again,

David,
I looked into what you mentioned and the site has Run process in II5 isolation mode unchecked and there are entries in the application pool.

Can you your application on IIS6 similar to IIS5 - no periodic
recycling. I'm not certain your application likes being restarted and
perhaps it has code or uses components that leak system-wide resources
unrelated to the process to eventually result in your state. It's all
guessing unless one captures a stack backtrace of what is going on
within the problematic process.
I see no reason why you need to restart IIS to get things working.
Recycling application pool is about all that's necessary. I consider
anything that requires restarting IIS a requirement of the custom
application, not IIS. The question is whether you know about the
custom requirement and how to manage it.
An in-place upgrade from IIS5 to IIS6 leaves it in IIS5 Compatibility
mode, so either you:
1. Did not do an in-place upgrade
2. Did an in-place upgrade but changed the settings to uncheck IIS5
Compatibility Mode
In either case, my question is whether you are certain that all parts
of your application and related dependencies support Windows Server
2003.
It is not clear to me whether you want to debug and determine the
cause of your application's failure, so that you can do something
better than restarting IIS, or if you are content to just admit this
application has bugs on Windows Server 2003 and restarting IIS is the
simplest solution you can think of until the application can be re-
written, or something else.

Are you running 32bit or 64bit Windows.
